Most hiccups will stop on their own. Home remedies are generally sufficient to resolve hiccupping. For persistent hiccups (lasting more than three hours) treatment varies, and you may need to contact your doctor. A physician may prescribe medications for severe, chronic hiccups.
In physics, a force is said to do work if, when acting, there is a displacement of the point of application in the direction of the force. For example, when a ball is held above the ground and then dropped, the work done on the ball as it falls is equal to the weight of the ball (a force) multiplied by the distance to the ground (a displacement). Work transfers energy from one place to another or one form to another.
Physics is a branch of science. It studies matter, and all forces and their effects. Modern physics connects ideas about the four laws of symmetry and conservation of energy, momentum, charge, and parity. The word physics comes from the Greek word á¼¡ ÏÏÏÎ¹Ï, meaning nature. Physics can also be defined as that department of knowledge which relates to the order of nature, or, in other words, to the regular succession of events.
